2011
This logo was adopted by everyone and everyone like this one. Still this logo is used everywhere and no change is happened in it until now.
When Symbol XBT ?
Symbol BTC created a problem as it violates the ISO 4217 because it starts with ‘BT’ , which is the country code of Bhutan.
Bhutan doest not use the code “BTC” for any currency but only Bhutan can used “BT” as first letters for code of its currency and others are restricted.
So Bitcoin community started with the new Bitcoin code as ‘XBT’ which was later started using by exchanges like Bitmex, Kraken as Bitcoin currency unit.
But XBT did not get much popularity as most of the Bitcoin community like the BTC code for Bitcoin and they started using BTC as Bitcoin currency unit.
After this Bitcoin got the two currency code as XBT and BTC , both are used to represent Bitcoin currency unit.
So, 1 BC= 1 BTC = 1 XBT = 1 Bitcoin
